UNITED STATES PATENT OFFICE CHARLES IB. OVERTON, OF VIGOR, VIRGINIA.

CHAIR.

Application filed June s,

This invention relates to self-propelled rolling chairs, and aims toprovide a rolling chair of a novel construction wherein the same may befolded into; a small and compact article to facilitate the storing andvA still further object of the invention is to provide a rollingchairwhich may be readily and easily folded to its inoperative andoperative positions.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed,- it being understood that I changes in theprecise embodiment of the invention herein disclosed, may be made withinthe scope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawings:

Figure 1 is a front elevational view of a rolling chair constructed inaccordance with the invention and showing the same in its operativeposition. v

Figure 2 is a front elevational view of the chair showing the same'in apartially folded condition.

Figure 3 is a side elevational view of the chair in its operativeposition.

Figure 4 is a perspective view illustrating one portion of the chair andshowing the axle construction in detail.

Figure 5.is a perspective view illustrating the brake.

Referring to the drawings in detail, the chair includes a pair of sidesections 5 and 6 respectively, the side sections being identical inconstruction and include spaced paral lel hars,7 and 8 respectively, thebars 7 being formed with cut out portions arrange-d adjacent tothe'rear. ends thereof, which cut out portions accommodate the axles 9which are of the stub type, and" provided with upwardly extendedportions 10 that are formed with openings to accommodate the bolts 11that pass through the upper bars 8.

At the rear of the bars 7 and 8 are vertical bars '12 to which the bars7 and 8 are secured, as by means of the straps 13, so

1926. Serial No. 114,495.

that the bars 7 and 8 are held in spaced relation with each other. i i

The forward ends of the bars 7 and 8 of each frame are connected bymeans of the bars 14 that have their lower ends extended below the'bars7, where they are provided with suitable sockets for the reception ofthe vertical shafts 15 thatare provided with I forks 16 and in whichtheufront or small wheels 17 are mounted.

Secured tothe under surfaces of the bars e 7 arev rearwardly extendedinclined barsf18 that h ave their rear ends spaced ,from the surfaceover which the rolling chair is moving, so that should the chair tiltrearwardly these bars 18 will act to stop such rearward tilting. Inorder to cushion'the movement of the bars 18, springs 19 are providedand disposed between the bars? and 18 as clearly shown by Figure 4 ofthe drawings.

At the rear end. of each bar 8 is a metallic strap 20 that has anupwardly extending end portion 21 adapted to'engage one edge of thevertical arm 22,, there being provided bolt openingsin the members 21and 22' for the reception of bolts to secure the arm 22 in position withrespect to its supporting member. f p v Atthe upper ends-of the arms 22are bifurcated members 23 adapted to grasp the ends of the upper bar 24of the seat back 25 so that the upper portion of the seat back will besecurely held against movement.

Bars 26 form the side bars of-the seat back 25 and have their lower endsreduced as at 27 and providing pins adapted to be positioned within. thekeepers 28 that are secured to the rear edge of the seat portion 29.;

This seat, portion 28 is formed with of the side frames of the rollingchair. 1

Thus it will be seenthat ,due to this con struction, the seat and seatback act to hold the side frames in proper spaced relation with eachother when thechair is in its operative position. 1

Brace bars 31 are employed at the front and'rear of the chair and have]their outer ends pivotally connected to the side frames of the chair, asclearly'shown by Figures 1 and 20f the drawings, the brace bars beingarranged in pairs and pivotally connected at 32. These brace bars act'to' prevent spreading of the framesection when the chair is in itsoperative condition, while the seat and back sections act to prevent thesections from movingtowar'ds each other.

The arms of the chair are indicated at 33 and have their rear endsconnected with the arms 22, the forward ends being con-- nected with theupper ends of the bars 34. that are secured to each frame of the chair.

The wheels that supportthe chair are indicated by the referencecharacter 35 and are mounted on the axles 9 as shown by the drawings.Operating frames indicated at 36 include pairs of bars formed with outwardly curved portions defining forks 37,.

the lowerends of the forksbeing formed with openings to permit the forksto be slid onto the axles 9 to connect the operating framesto the axles.

One of the bars of each frameSo extends inwardly and upwardly providinga. cleargated openings 44 to accommodate the bolt 45 that also passesthrough the arms 33. Thus it will be seen that by lengthening the chainconnectingsprockets 42 and 43, the bearing member 39 may be movedupwardly. The foot rest of the chair is in;-

dicated by the reference character &6 and is supported by means of thedownwardly extended bars t? that are pivotally con nected to the framesat 48, and al o have pivotal connection with the foot rest 46 at 49 sothat the bars l? may be moved towards each other when the rolling-chairis to be moved to its folded position. The foot rest is also bracedagainst rearward movement by means of the bar 50 that is shown in Figure3-as extending rearwardly where it connects with the axle, the forwardend be ing connected with the foot rest 46.

A brake rod indicated at 51 is shown as supported adjacent to one of thearms 33 and has swivel connection with arm 52 which is pivotallysupported by means of the pivot pin 52, and on which the shoe 53'ismounted to engage the wheel 35 associated there with when the handle 54at the upper end of the rod 51 is forced downwardly, thereby braking thewheel 35.

A lever 56 is shown as formed with a curved end 57 d-enninga shoemounted ad jacent to and designed to engage the wheel' at theoppositefside of the chair. This leyer 56 connects with the brake rod 51through the link 58 and-laterally extended arm 59, there being provideda coiled spring 60 connected with the arm 59 to return the arm 59 to itsinitial position after it has been actuated. Thus when it is desired tooperate the brake 57, the rod is rotated by means of the handle 54.

When it is desired to brake both wheels simultaneously, the rod 51 isforced down wardly and rotated at the same time.

From the foregoing it will be seen that to fold the chair, it is onlynecessary to remove the seat and seat back from their positions betweenthe side frames of the chair, and remove the lower bracing bars 31 attheir points of connection with the side frame, whereupon the sideframesniay be moved towards each other and the device folded into asmall and co npact'article.

I claim: p I 1. A folding rolling chair including side frame sections,means for pivotally connect-- ing the sections, a seat. and seat backremovabiy connected, said seatand seat back being supported by theframes and adapted to hold the frames in spaced relation with eachother, and wheels for supporting the frames. 7

2. A folding rolling chair including frames, each of said framesembodying parallel upper and lower bars,'means for holding the bars inspaced relation with each other, means for pivotally connecting theframes, and a removable seat and seat back arranged between the framesand sup ported thereby.

3. A folding rolling chair including frames, said frames beingwheel-supported, pivoted bars for connecting the front and rear ends ofthe frames, a seat section adapted to be positioned on the frames, saidseat sections having keepers on its rear edge, a

seat back having reduced portions adapted to extend into the keepers, tohold the seat back to the seat, and means for securing the seat backagainst movement at its upper end.

i. A folding rolling chair including frames, means for pivotallyconnecting the frames to permi the frames to be moved towards and awayfrom each other, each of said frames includmg a rear upwardly :rtendcdarm, said arm having bifurcated end portions,a seat positioned on theframes, I

a seat back removably connected with the seat and having the upperportion thereof arranged betweenthefurcations of the bi furcatedportions of the arms, and wheels for supporting the frames.

In testimony that Iclaim the foregoing as my own, I have hereto'aliixed'my signature.
